Robertson fell to 2-5 and blew his fourth save chance in 40 opportunities.
Having lowered his ERA to 3.81, Kuroda will take on the Blue Jays at home Friday.
Beltran, who hasn't played since Tuesday, recently decided he would wait until the offseason to have surgery to remove a bone spur from his right elbow.
"[The elbow is] feeling better every day," Eveland said. "I hate to leave here, because I do feel like, you know, maybe in another week or so I'd probably be able to pitch again."
Eveland had a 2.63 ERA, 1.10 WHIP and 8.9 strikeouts per nine innings in 30 appearances for the Mets.
"He's all right. He's a catcher," Melvin said.
Norris went 0 for 3 with a walk and a strikeout Sunday at Seattle and is batting just .238 (39 for 164) with two home runs since the All-Star break.
"He took one off the mask earlier in the day, but at the time, he didn't show the reaction that is normally associated with someone that's been concussed," manager Brad Ausmus said. "He kind of went about his business. And it wasn't until he actually went to hit his last plate appearance that someone said to me that he didn't seem right on the bench."
Avila struck out on three pitches and, when questioned upon his return to the dugout, complained of a headache. He went 1 for 3 with a walk and two strikeouts in the contest.
Avila traveled with the team to Minnesota after the game, but Ausmus told mLive.com he likely wouldn't play Monday against the Twins.
"He's fine. He got called away from this game," manager John Farrell said. "There was a family emergency that he had to attend to and he jumped on a flight late this afternoon."
Farrell added that Ortiz should rejoin the team Tuesday at Pittsburgh.
His status going forward is unknown. He'll have an MRI on Monday.
"This is a young player where we had something going, missed a couple of months and all those are reasons for us to once again pause and just kind of take our time, make sure everything looks right before moving forward," Matheny said.
Wacha has made two starts in September after missing all of July and August with a stress fracture in his right shoulder.
